The HARPS search for southern extra-solar planets: XLIII. A compact system of four super-Earth planets orbiting HD 215152

We report the discovery of four super-Earth planets around HD 215152, with orbital periods of 5.76, 7.28, 10.86, and 25.2 d, and minimum masses of 1.8, 1.7, 2.8, and 2.9 M · respectively. This discovery is based on 373 high-quality radial velocity measurements taken by HARPS over 13 yr. Given the lo...
